9 Redox Reactions The term Reduction originates from the concept of reducing an ore, usually a metal oxide, to its elemental form, usually the pure metal. For example: Iron is made from iron ore, the iron reaction is: 2+Fe 3++ 2 Fe + 8 e– 3 Fe and the carbon monoxide reaction is: 4 CO – 2+4 CO + 8 e Here the oxide ions are spectators, transferring from the iron to the oxidized carbon.
